DELIVERY OR FLY FINGER FOR PRINTING-MACHINES.

SPECIFICATION forming part of Letters Patent No. 428,025, dated May 13, 1890.

Application filed July 31,1888. Serial No. 281,598. (No model.)

To all whom it may concern/.-

Be it known that I, HADWEN SWAIN, a citizen of the United States, residing at San Francisco, in the county of San Francisco, State of California, have invented certain newand useful Improvements in Delivery or Fly Fingers for Printing-Machines, of which the following is a specification,reference being had therein to the accompanying drawings.

This invention relates to certain improvements in printing-presses; and it has for its objects to provide the same with a series of adjustable fly or delivery fingers and means for clamping the same to the rock-shaft by which they are operated, as more fully hereinafter set forth.

The above-mentioned objects I attain by the means illustrated in the accompanying drawings, in which- Figure 1 represents a side elevation of a clamp whereby the fly or delivery finger is secured to the rock-shaft. Fig. 2 represents a similar view of a modification of said clamp. Fig. 3 represents a transverse sectional view of the clamp, showing the seat for the fingers Fig. 4 represents a cross-section of one of the fingers, and Fig. 5 represents a view of one of the clamps and fingers complete in side elevation.

Referring to the drawings, the letters A B indicate the jaws of the clamp, one of which is provided with a longitudinal angular rib C, and the other with a corresponding angular longitudinal groove D.

E indicates the fly or delivery finger, which is constructed of sheet metal struck up into provided with half-sockets I, which may be either angular, polygonal, or semicircular, so as to fit the rock-shaft J, which operates the fingers, and secure said fingers adj ustably thereto.

Ilavin g thus described my invention, what I claim, and desire to secure by Letters Patent, is

1. The combination, with a detachable flyfinger constructed of sheet metal and angular in cross-section, of the clamping-jaws, one having an angular rib and another a corresponding groove, between which the finger is clamped, and a clamping-screw, whereby the jaws are clamped together, substantially as specified.

2. The combination, with the rock shaft carrying the fiy-fingers of a printing-press, of thehalf-socketed clampsand clamping-screws, whereby the clamps-and their fingers are secured to the shaft, substantially as set forth.

In testimony whereof I afiix my signature in presence of two witnesses.
